I wonder, should we expect FFmpeg to already be referenced by somebody's
profile if they are using youtube-dl? VLC and mpv both depend on FFmpeg.
The use case of "download video and watch it on another machine (or
never watch it)" seems somewhat esoteric.

On the other hand, youtube-dl has no explicit dependencies — I guess
that everything it needs is from Python. That's beautiful, and I
understand the reluctance to add a dependency, especially on a "kitchen
sink" package like FFmpeg.
